Charcot-Marie-Tooth, or CMT, is the most commonly inherited neurological disorder. It was discovered in 1886 by three physicians, Jean-Martin-Charcot, Pierre Marie, and Howard Henry Tooth. It is a form of muscular dystrophy.
CMT patients slowly lose normal use of their feet/legs and hands/arms as nerves to the extremities degenerate and the muscles in the extremities become weakened because of the loss of stimulation by the affected nerves. Many patients also have some loss of sensory nerve function.
CMT usually isn’t life-threatening and almost never affects brain function. It is not contagious, but it is hereditary and can be passed down from one generation to the next.
